The benzylation reaction of p-octyl phenol alkoxylates with alkyl halide is a crucial step in the synthesis of alkylphenol ethoxylate-based surfactants. In this research paper, we investigate the impact of different mole ratios of ethylene oxide to p-octyl phenol on the benzylation reaction and the properties of the resulting products. The reaction study involves the formation of alkoxide of different mole ratios ethoxylates of p-octyl phenol and subsequent benzylation using benzyl chloride as the alkylating agent. The mole ratios of ethylene oxide to p-octyl phenol employed for reaction study ranges 1:11 and 1:15 to 1:19. The synthesis was carried out using a batch reactor under controlled conditions. The reaction conditions, such as temperature, reaction time, and reactants mole ratio, are carefully optimized to achieve high conversion and selectivity. The products are characterized using analytical techniques such as cloud point, hydroxyl value by titration method and molecular weight of initial and synthesized product. Furthermore, the paper discusses the implications of the obtained results in terms of the potential applications and properties of the benzylation products. The modified ethoxylates could find utility as surfactants, emulsifiers, or functional additives in various industries. Overall, this research paper provides valuable insights into the benzylation of p-octyl phenol ethoxylates with benzyl chloride. The findings contribute to the understanding of this chemical modification process and offer potential avenues for the development of tailored ethoxylate-based materials with enhanced properties.
